Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel virus which has caused an ongoing pandemic since 2020. It is estimated that 15% patients may develop severe pneumonia, 5% develop acute respiratory distress syndrome (ARDS), septic shock, and multiple organ failure. Anisodamine hydrobromide is a muscarinic receptor antagonist, and also shows anti-inflammatory effect. It has been approved in China to be used in patients with septic shock, organophosphorus poisoning and smooth muscle spasm. We describe three patients with positive results of NATs for SARS-CoV-2, persistent shortness of breath, reduced oxygen saturation and impaired physical endurance even after long-term routine treatments, who were diagnosed with Corona Virus Disease 2019 (COVID-19) infection. After the patients were additionally administrated anisodamine hydrobromide (20 mg twice daily) intravenously for 5 consecutive days based on the original routine treatments, the conditions of COVID-19 infection were rapidly improved, with ameliorated shortness of breath, coughing and sputum, increased oxygen saturation, and improved physical endurance. No obvious adverse effect was observed. Anisodamine hydrobromide might hold great prospect for potential clinical applications in treating COVID-19 patients and improving their conditions.
